"The Transportation Security Administration announced Tuesday that U.S. airline passengers will soon be allowed to carry small knives in their carry-on bags, a move that prompted swift condemnation from a flight attendants union.

The union for Southwest Airlines flight attendants called the decision "dangerous" and "designed to make the lives of TSA staff easier, but not make flights safer."

The changes were made public by TSA Administrator John Pistole during an aviation conference in New York.

Starting April 25, passengers going through U.S. airports can bring on board Swiss Army-type knives -- specifically, ones with blades no longer than 2.36 inches."

This will be nice for those of you who do carry on for their fly-in backpacking trips. I hope they allow small fixed blades and not just non locking folders.
